JAMES J. ALLISON, OF NELSON, ILLINOIS.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 228,582, dated June 8, 1880.

Application filed October 17, 1879.

To all whom it may concern:

Be it known that I, JAMES J. ALLISON, of Nelson, in the county of Lee and State of II- linois, have invented a new and Improved Bottle-Stopper, of which the following is a specification.

Figure 1 is a vertical sectional elevation of a bottle-neck, showing the position of the stopper when stopping a bottle. Fig. 2 represents the position of the stopper when the contents of the bottle are .being poured out. Fig. 3 is a vertical elevation of the stopper, partly in section.

Similar letters of reference indicate corresponding parts. a

This invention relates to that class of stoppers that automatically close the bottle.

The invention consists of a piece of springwire that is bent double in the middle, formin g an eye, and has its ends bent outward and down again to form two open sideloops with free ends, whereby a double spring is obtained.

In the drawings, A represents the wire with its central bend or eye, a, and its two open side loops, 1) I), with free ends I) I). B is the button securely fixed upon the wire A, and O is the elastic disk fixed in the annular groove 0 of the button B.

This stopper is introduced into the bottle D by placing the button end in first, and by then pressing down upon the bends of the open loops b b, so that the two arms (I of the wire A shall overlap each other, as shown in Fig. 2, and when the said stopper is held in this position the bottleD can be filled or emptied.

On removal of the pressure from the bends of the open loops b b the elasticity of the wire A forces the inclined outer faces of the said open loops 1) 1) against the inclined plane of the inside of the lip of the bottle D, and thereby causes the button B to be drawn upward into the narrow part of the neck of the bottle D, so that the elastic disk 0 shall be pressed out against the sides of the said neck, as shown in Fig. 1, and make an air and water tight within-described bottle-stopper, consisting of a grooved button, B, in the groove of which an elastic disk, 0, is fixed, and of a doubled wire, A, provided with open side loops, 1) b, having free ends I) b, on which, near its central bend or eye, the button B is centrally fastened, substantially as herein shown.
